HARROW OR SIMILAR IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 741,596, dated October 13, 1903.

Original application filed October 27, 1902, Serial No. 128,962. Divided and this application filed March 2, 1903. Serial 110.145,?54. (N0 model.)

T0 at whom it may concern.-

Be it known that 1, WILLIAM F. SHEPPARD, a citizen of the United States, residing at Washington, in the District of Oolumbia,liave invented certain new and useful Improvements in Harrows or Similar Implements;v

and I do declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in convertible harrows and cultivators; and it consists in the peculiar construction and combination of devices hereinafter fully described and claimed.

This invention is a division of my application for Letters Patent of the United States filed October 27, 1902, Serial No. 128,962.

The object of my present invention is to effect improvements in the construction of the adjusting-lever employed to adjust the teeth or shovels.

In the accompanying drawings, Figure lis a vertical longitudinal sectional view of the convertible harrow and cultivator embodying my improvements. Fig. 2 is a detail view of the same, showing a different arrangement of the adj usting-lever.

Within the scope of my present improvements the harrow or cultivator to which my improved adj usting-leve'r is attached may be of any suitable construction.

In the convertible harrow and cultivator here shown, A represents the frame; B, the cross-bars, which carry the cultivator or harrow teeth 0, and certain of the said cross-bars which are journaled in suitable bearings with which the frame is provided are provided with rock-arms D. One of the said cross-bars or rock-shafts is provided with an adj usting-' lever 1, the same comprising an upper section 2 and a lower section 3, detachably connected thereto and here shown as connected thereto by bolts 4. The upper section of the lever is pivotally connected to a link 5, as by a bolt 6, and the said link is also pivotally connected to the rock-arms D. The lower section 3 of the lever is of substantially quadrant shape and is provided with an opening corresponding in size and shape to the cross-sectional area of one of the rock-shafts, so that the lat:

ter may be passed through the said openings. The said lower section of the adjusting-lever is reversible-that is to say, it may be disposed to extend either to the front or the rear of the rock-shaft to which it is connected, as shown in Figs. 1 and 2. When the lower section of the lever is disposed as shown in Fig. 2, shorter harrow or cultivator teeth may be employed than when the adjusting-lever is disposed as shown in Fig. 1. The link 5 is provided with a segment-rack 7', and the adjusting-lever is provided with a s pring-pressed locking-dog 8 of the usual construction to coact with the segment-rack, and hence secure the adjusting-lever at any desired adj ustment. Since the adjusting-lever is pivoted to the link-rod, which is connected to the rockarms of certain of the rock-shafts, said lever is provided with a shiftable fulcrum, as will be understood.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of myinvention willbe readily understood, it is thought, without requiring a more extended explanation. I

I do not desire to limit myself to the precise construction and combination herein the combination of a plurality of tooth-carrying rock-shafts, a lever having a. quadrantshaped lower portion. detachably connected to one of the rock-shafts, rock-arms on the other rock-shafts, and a link-rod connecting the said rock-arms and lever together, said latter, substantially as described.

3. In combination, in an implement of the In testimony whereof I have hereunto set class described, with a tooth-carrying rockmy hand in presence of two subscribing Witshaft, a lever havinga detachably reversible nesses.

quadrant-shaped lower section, detachably WILLIAM F. SHEPPARD. 5 connected to the rock-shaft, and a shifting Witnesses:

fulcrum for the said lever, substantially as J. O. WILLSON,

described. BENJ. G. COWL.
